Refrigerated open showcase



FIG. 1 is a perspective view of a refrigerated open showcase my new design;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof, the left side elevational view being a mirror image thereof; and,

FIG. 4 is a top plan view thereof.

The broken line showings of the wheel assemblies, and the truncated cone-shaped spacers on the rear of the showcase, are for illustrative purposes only and do not form part of the claimed design. The rearwardly-facing back surfaces and the bottom-facing surfaces of the showcase also do not form part of the claimed design. 

The ornamental design for a refrigerated open showcase, as shown and described.
